Books have been stated on this topic, and the controversy and disharmony about where the "hot" one armed bandits are installed in the casino are still raging – over 60 yrs after the slot machines were first placed in gambling dens.
The classic rule is that the more favourable slot games were put just inside the main entryway of the casino; so that folks going by would see jackpot winners … be infatuated enough to come inside and play. Our inference is that this is definitely no longer so.
Just about all of the mega casinos nowadays are oversized complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot machines close-by any entrances or exits.
Another standard rule is that loose slot machines are installed on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be inspired to play. Notably though, we find that this also is not a universal rule any more.
What casinos found over the years is that people walking down the busy aisles were frequently on the way to somewhere else. If they played slot machine games at all, they would simply put in their loose change because they happened to be walking by. Win or lose, they would very often not stop to keep playing. And the last thing a casino wants is for someone to win a jackpot by playing only a few coins and then not stay to put it all back in!
Today, casinos are constantly changing their perspective about where to place the loose slot games.
